Abstract

The invention relates to a ground resistance real-time monitoring device, which comprises a switching power supply, a ZIGBEE system, an AC pulse constant current source, a collected data processing unit and a data array unit. According to the ground resistance real-time monitoring device, current emitter poles and voltage test poles adopt an anti-corrosion high-conductivity material, and are buried underground permanently; and when ground resistance change surpasses requirement, an alarm can be given, and the test data is transmitted to a client data center through a network. According to the ground resistance real-time monitoring device, during early-stage construction, the current emitter poles and the voltage test poles for testing are pre-buried in groups according to environment and geographical positions at that time, and thus collection of test data at different positions can be finished through one test. The ground resistance real-time monitoring device can reflect the ground resistance of a grounding grid comprehensively.

Example Embodiment

[0019] The present invention will be described in detail below with reference to the drawings.
[0020] The grounding resistance real-time monitoring device of the present invention is composed of five parts, namely: a switching power supply, a ZIGBEE system, an AC pulse constant current source, a data acquisition processing unit, and a data array unit.
[0021] Specifically: the switching power supply can process the mains power into 5V, 1A output to the entire system.
[0022] The ZIGBEE system can generate excitation signals, process received data signals, and display and transmit data.
[0023] The AC pulse constant current source can amplify, isolate and filter the excitation signal generated by the ZIGBEE system and output it to the data array unit.
[0024] The acquisition data processing unit can collect the voltage obtained between the voltage test electrode and the test ground pile after the signal emitted by the current emitter passes through the ground grid, filter, shape and transmit it to the ZIGBEE system.
[0025] The data array unit can transmit the AC pulse constant current source signal to different current emitters in time intervals.
[0026] In the foregoing specific embodiments, the current electrode and the current emitter both represent the current emitter; the voltage electrode and the voltage test electrode both represent the voltage test electrode; the test pile and the test ground pile both represent the test ground pile.
[0027] Obviously, the above-mentioned embodiments are merely examples for clear description, and are not intended to limit the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is unnecessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the protection scope created by the present invention.
